| Abstract | ||
| One of the ways to use solar energy is to use a solar dryer. But these kind of dryers have low efficiency that optimizes their absorbent plate to increase efficiency and save energy. For this purpose, the air flow inside the compartment of the adsorbent plate of the solar dryer was simulated using the computational fluid dynamics modeling and the heat transfer process, flow distribution and air velocity inside the compartment were analyzed and finally, the plates were compared in vitro. In this research, three different modes of the page with the same input and three different output modes (circular, conventional and perforated) were investigated. In a porous sheet with porosity, the plate was used with a coefficient of 0.0314. The results showed that between analytical and empirical data, the explanatory factor (R2) was above 97%. There are circular and conventional heat accumulation in the corners, which, by changing the type of output and converting it to the perforated output state, Heat and heat accumulation are prevented. | ||
